Small groups devise a plan to find the bag that contains the larger percentage of blue chips. they then institute their plans and compare results to the actual quantities in the bags. 

Where does the water we use come from? To understand the concept of a watershed, class members study the water cycle and then engage in an activity that simulates a watershed.

You won't want to flush a great lesson down the drain! An intriguing resource asks learners to predict the number of sheets of toilet paper on a roll. Presented with the dimensions of the roll and one sheet of paper, scholars make...

Little learners experiment with sunlight and map out how light travels. Using a mirror and slotted card, they find out about items that can reflect or absorb the light. They experiment with a variety of materials to find out how light...

We chew with our teeth every day, but how much do we really know about them? Allow Ms. Frizzle to teach your kids a thing or two about teeth. Kids complete a prereading exercise, read the book, and respond to several prompts about the...

What would a meal be without the taters? The question is, how long does it take to peel those potatoes? Given the rate of peeling one potato, scholars predict the time it takes to peel the bag. The twist is that the first potato was...

Get into the swing of things. Pupils use a pendulum to demonstrate the conversion of potential energy to kinetic energy and back. After measuring the speed of a pendulum and compare it to the calculated theoretical speed, they...

Make solutions to projectile motion problems magically appear using equations. Pupils watch a clip from a Harry Potter movie and find the length of time it takes for a remembrall to fall into Harry's hands. They use a projectile motion...

Slide books with a little assistance from Newton. Using books, groups create a demonstration of Newton's Second Law of motion. Pupils compare the distance traveled by one and two books when they apply a force to them.

Tired of waiting for hot water? Groups of three determine the efficiency of an electric water-heating device. They calculate the amount of energy it takes to heat the water and the theoretical amount of energy required to heat the water....

Plop, plop, fizz, fizz, oh that one is the fastest. The teacher demonstration is the second part of a four-part series. The class observes how different pill types dissolve in simulated stomach acid. They determine which one dissolves...

How do people determine if something is acidic or basic? Learners make their own acid-base indicators using red cabbage and then determine the acidity and alkalinity of different substances. First, they test substances of known pH and...

High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates...

Compounds take on different properties than their elemental components. How can scientists determine those elements? A lab-based activity has learners explore several double replacement reactions to analyze compounds qualitatively. They...

After considering the role that gasoline plays in our lives and our dependence on it as a society, learners participate in a reading activity discussing why oil prices are increasing. They will then simulate being members of a committee...
